<P>PROBLEM TO BE SOLVED: To provide a computer program capable of preventing endless execution of an undesirable instruction in case that the execution order of processing in a computer is not right. <P>SOLUTION: Storage data of an address A1 are stored in a work register R4 before calling a memory erasing processing program in a program of a call origin (steps ST101 and ST102). In the memory erasing processing program, it is determined whether the storage data in the address A2 and in the register R4 are equal to each other or not (step ST205) prior to execution of a memory erasing instruction (step ST206). When these storage data are equal to each other as the result of determination, the memory erasing instruction is executed (step ST206), and when it is determined that these storage data are not equal to each other, the processing is returned to the program of the call origin without executing the memory erasing instruction (step ST209). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
